The Whites added another winger to their squad this summer by roping in long-term target Daniel James from Manchester United on a permanent basis.
With the Welshman in the squad, it has been a topic of discussion among the Leeds faithful how Bielsa will use him this season, with first choice wingers Raphinha and Jack Harrison being fixtures under the Argentine in the Premier League.
There have been suggestions that Bielsa could move Raphinha to a number 10 role from the wing, but ex-Leeds boss Grayson has stressed that it would be a strange decision as there are no previous examples of the Brazilian being successful in midfield.
Grayson explained that Raphinha could suffer from a lack of space in the middle of the park if he is deployed there, which could hamper his impact on the pitch.
Asked about his thoughts on suggestions that Raphinha could play in the number 10 role, Grayson said on BBC Radio Leeds: “No, [we do not have any examples of Raphinha playing in the number 10 role at Leeds].
“It is a strange one because you see a player that has got great ability, can find a pass, can run with it, sometimes go into the middle of the pitch and there are too many people around him and they do not get the space to go on 1v1 and go inside outside as a wide player can do.
“But there is obviously some thought process in bringing Dan James, who has not been brought to the football club to sit around on the bench.
“So, he is going to play at some point in one the wide areas.
“Jack Harrison has done really well for the club over a number of seasons and now Raphinha has been Leeds’ best player arguably as well.
“So, you have got three out and out wide players. Who is going to play in that 10?
“It is an interesting role.
“That is why Marcelo is there doing what he does.”
Bielsa has been using the likes of Rodrigo or Tyler Roberts as a creative hub behind striker Patrick Bamford, and it remains to be seen whether Raphinha will be moved to midfield as the season progresses.
